Doctoral Researcher (f_m_x) – Hydro-Geophysics (Geowissenschaftler/in)

GFZ is Germany's national centre for solid Earth research. We advance the understanding of dynamic processes to address global challenges, from mitigating the impacts of natural hazards and sustaining our habitat amid global change to responsibly managing georesources. We are part of the Helmholtz Association, the largest German scientific organisation. With around 1,200 employees as well as ca. 500 guest researchers, we contribute to the Helmholtz Research Field Earth and Environment, aligning cutting-edge research with societal relevance and international collaboration. Our work integrates multidisciplinary studies across Earth's system components, leveraging advanced technologies and infrastructure to research solutions and to transfer our knowledge to society. We are doing this in line with our vision: “Taking the pulse of our Earth to safeguard a habitable planet”. For section 4.4 "Hydrology" ( https://www.gfz.de/en/section/hydrology/overview ) (department 4 “Geosystems” ( https://www.gfz.de/en/departments/geosystems ) ), we are looking for a: Doctoral Researcher (f_m_x) – Hydro-Geophysics Reference Number 11554 This position is part of the Research Unit “RING: Rotation in Physics, Geodesy, and Geophysics” ( https://www.ringlaser.de ) , funded by the German Research Foundation (DFG). RING brings together expertise from several universities, research institutions and a Federal Agency across Germany to improve measurements with laser-optical instruments to observe changes in Earth rotation. The overall goal is to use these observations to enhance geodetic and geophysical applications, such as quantifying mass variations in the Earth system by climate variability and change. The open position is part of the RING project P6, which analyses the effects of atmospheric and hydrological dynamics on long-period rotational measurements, as a joint effort of GFZ, the German Federal Agency for Cartography and Geodesy (BKG) ( https://bkg.bund.de/en /) and the Karlsruhe Inst
